One of the most common problems encountered in vegetable seedling production is "damping-off". Damping off is a disease that results in the rotting, collapse and finally death of seedlings just before or soon after they emerge. It often starts out in a few plants but can spread quickly throughout the entire flat and into neighbouring flats.
One or more soil-borne pathogens may be responsible for this disease, depending on the environmental conditions in the greenhouse.
Soil-borne pathogens such as Pythium and Phytophthora, often called water molds, can be particularly destructive if the soil is kept too wet for a long period of time. Although temperature is important, different species of these so-called water molds can infect at different temperatures. Pythium is the most common water mold pathogen found on diseased greenhouse vegetable seedlings and is often associated with excessive nutrition or ammonium toxicity.
